Best Grip Trainers 2026: I Tested 5 To Fix My Slice

4 of them made my golf worse. Only 1 of them actually worked.

5 trainers, 5 months, one launch monitor, same club and same range every session. Paid for out of my own pocket. Nobody sponsored a word of this.

By Marcus Hale | Golfer for 22 years | Updated September 2026

“You’ve Been Playing 22 Years And Still Slice? I Thought That Was A Beginner Thing.”

My buddy’s son, Alex, said that to me…

He’d been playing for 5 months, and just beat me by 4.

He wasn’t trying to be mean. That was worse. It was a genuine question.

I walked off the course and sat in my car with the radio off for a long time.

22 Years. “Perfect Swing.” The Ball Still Went Sideways.

I know what a neutral grip is. I could draw you one on a napkin.

I’ve had my swing filmed a dozen times. Every time, the pro handed the phone back and told me there wasn’t much to fix.

So I did what everybody does with a swing that’s supposedly “fine.”

$200 lessons.

YouTube tips at night.

Even a $450 draw-bias driver my wife still hates me for buying.

My swing got better on video. My ball never got better in the air.

I still walked up to every first tee with a knot tied in my stomach.

3 guys watching me tee it up.

And in my head I’m already running the coin flip…

Straight down the middle, or into the trees on the right?

They Stopped Giving Me Putts

Inside 3 feet, my buddies used to give me a gimme.

Last season they started making me hole every one.

Nobody looked at me when they did it.

11 years I’ve played with these guys. Now they don’t think I can make a 3-footer.

The 4 Grip Trainers In My Junk Drawer

My hands are big. I wear an XL glove. I’ve played jumbo grips for years.

So when I finally accepted my grip was the problem, I bought a grip trainer.

Then I bought another one…

And eventually there were 4 of them in a drawer in the garage.

My brother-in-law started calling it the graveyard. He’d ask what was in the box before I got it open.

By the 4th one I stopped telling anybody I’d bought it.

The thing I actually believed by then was that my hands were the problem. That I’d been handed the wrong genes for this game.

But after what a club fitter showed me, I realized NONE of this was my fault…

And if it’s happening to you, it isn’t yours either.

You didn’t fail grip trainers. Every one of them failed to be built for YOU.

And there’s one reason for that, which took me 22 years to learn.

I’m going to tell you below. But before I do, let me explain how I got here.

My Grip Was Never The Question

I know the grip is what matters…

After all, there's a reason Scottie Scheffler warms up with a grip trainer before every tournament.

That was never the question.

The question was why every one I bought felt like it was molded around somebody else’s hands.

So I stopped guessing and started measuring.

The Man Who REFUSED To Sell Me A Training Aid

I called Dale Kirby.

Dale fits clubs for a living. He works on a few thousand golfers' hands a year, and he owns the calipers to go with it.

He doesn’t sell training aids. He told me flat out that he never will.

Dale Kirby

Then he told me the thing nobody had told me in 22 years.

Your hands slide off neutral a few degrees at a time, and you never feel it happen.

By the time the ball tells you, it’s already gone right.

A trainer exists to LOCK your hands there so they can’t slide.

That’s its ONLY job.

But here’s why most fail.

Why Grip Trainers Fail

“A grip trainer is a grip trainer, right?”

That’s what I thought before this. That they’re all molded for the same neutral grip, that any one off the shelf would work.

Then Dale said the part that reorganized 5 months of my life.

He held up 4 fingers.

Dale Kirby

The neutral mold is the same. These are the things that actually matter when buying one:

4 of the 5 I tried failed at least one of those.

What I Tested

Same protocol on all 5. Same driver, same jumbo grip, 20 recorded swings on the launch monitor, 4 range sessions each.

And one number, because one number is all this needs.

How many of my 20 drives finished straight.

Off my own bare hands, before any of it: 3 out of 20.

That’s what everything below is measured against.

The Type I Refused To Buy

There’s a whole category I ruled out before I spent a dollar. The ones that bolt on and never come off.

I’d have to SACRIFICE my $300 club to a $30 piece of plastic just to use them.

That was the end of that conversation.

#5 · The $17 One Off Amazon

1.8 / 10

SNAPPED · 9 straight, then it was in pieces.

I started where everyone starts. Cheapest one with decent reviews, 2-day free shipping.

And it worked…

9 of my 20 drives finished straight, up from 3. For 6 days I felt like I’d finally figured this game out.

Then on a Tuesday, mid-swing, it cracked in half like a toy out of a cereal box.

Half of it hit the mat. The other half stayed on the club. A piece went past the guy in the next bay. He picked it up and handed it back to me without saying anything.

Dale Kirby

It showed me what my hands were supposed to feel like, then it took it away.

Bottom line: the only one that ever felt right, and it was in the trash 6 days later.

#4 · The One That Felt Like It Was Built For A 10-Year-Old

2.6 / 10

SHREDDED · 4 straight out of 20.

I went up in price. Better brand, better packaging, better reviews.

It’s sold for grown men. It does not feel like it was built for one.

And I could not get my fingers into it.

It squeezed my ring finger and my little finger together so hard that after 20 balls I had a blister opening up on the inside of my hand. I had that finger taped for 9 days.

I couldn’t even hold a golf club for a week because of how it mangled my hands.

Dale measured it against my hand. The molded channel was cut for a hand 3 sizes under mine.

Dale Kirby

And this is the one that did the real damage, because I didn’t blame the trainer.

I looked down at my own hands and decided they were the wrong shape for golf.

I carried that around for months. Because of a $30 piece of plastic molded for a child.

Bottom line: it took skin off my hand, then 9 days off my season, and made me think the problem was me.

#3 · GolFix. 11,000 Reviews. It Made Me Worse.

3.4 / 10

SLIDES · 2 straight out of 20.

Big name. 4 and a half stars.

11,000 people gave it 5 stars. Not one of them has my hands apparently.

Because it sat fine standing still. Then I’d take it back and it would slide around the shaft like a bar of soap.

So every swing put my hands somewhere slightly different. And every one of those got drilled deeper.

I wasn’t practicing a bad grip. I was practicing a new bad grip on every swing.

4 sessions. About 240 swings. 240 reps of a moving target.

I went in hitting 3 straight out of 20.

I came out hitting 2.

It WASTED 4 sessions and handed them back worse than it got them.

Bottom line: I paid $34 to teach my hands to be somewhere wrong 240 times.

#2 · “One Size Fits All.” But Not Me.

4.7 / 10

DOES NOT FIT JUMBOS · 0 swings recorded.

It said one size fits all right there on the box…

Unless you play jumbo grips.

It physically would not go on. I stood in the garage working at it for 10 minutes, then stopped before I broke something.

One size fits all, unless you have full-grown man hands and the grips that go with them.

I’d already paid for it. I’d already waited 4 days for it. And I found out standing in my own garage instead of in the listing.

Nothing on that box says what size grip it stops at.

Dale says he sees it constantly. Oversize and jumbo are the most common regrip he does for anyone past 45 years old. Almost nothing in the training-aid aisle is made for them.

And this is the one where I started making excuses.

That box went in the drawer with the other 3. Then my brother-in-law asked me to play twice that month, and I told him I was busy both times.

I wasn’t busy.

I just couldn’t face 4 more hours of apologizing on the tee.

Bottom line: 0 swings, 0 data, and 2 Saturdays I lied my way out of.

#1 Of The Failures · The SKLZ. It Worked. That’s The Problem.

5.1 / 10

TURNED MY SLICE TO A HOOK · 8 straight, and the rest were hooks.

The SKLZ fit my hands. It cleared my grips. It held where I put it.

And for 2 weeks I thought I’d found it.

The slice was GONE, like it was never there. I told my brother-in-law to book us a tee time.

Then The Ball Started Going The Other Way

Week 3, I pulled one 30 yards left of the pin.

Then another.

8 of my 20 drives finished straight, up from 3. Every single one of the other 12 was a HOOK.

I couldn’t work out what was happening, because the trainer was doing exactly what the box promised.

The problem was, it OVER-CORRECTED my slice into a hook.

Worse than when we started.

A slice you can play around. Sort of. You aim left and live with it.

A HOOK comes out low and it runs, and it doesn’t stop until it hits something.

On the 6th I put one so far left it finished on the next fairway, and I had to walk over and apologise to 4 guys I’d never met while they stood there waiting on me.

Bottom line: the only one of the 4 that fit properly and held on, and it’s the one that had me apologizing to strangers on a hole I’ve played a hundred times.

#1 · GameSwing TrueGrip 2.0

I opened the box expecting to be robbed again.

I Checked It Before I Used It

First thing I did was take it to the garage and try to get it on my driver.

It went over my jumbo grips.

With a satisfying click, it snapped right on.

Then I put my hand in and my palm didn’t hang off the end. It actually FIT my hands.

Then I did a practice swing, and it stayed right in place. No sliding.

Then I pulled it off, clipped it onto a 7 iron, and it fit perfectly on that too.

All 4 tests passed.

What Dale Found

It fits standard through to jumbo. That’s a measurement he took himself, not a line off the box.

It’s a stress-tested polycarbonate blend. Dale said you can feel that in your hand before you swing it, and that the one that snapped on me had been made of cheap generic plastic.

Both hands lock in, and it stays locked through a full swing, not just at address.

It clips onto any full-swing club and stays there until you take it off.

Dale Kirby

3 Straight To 16

12 sessions in, Dale pulled the numbers.

I started this whole thing hitting 3 straight out of 20.

On the TrueGrip I’m hitting 16.

Same club. Same range. Same monitor that watched the other 4 hurt me.

Straight Drives Out Of 20. Same Club, Same Range.

Every row is 20 recorded swings, same driver, same range, same monitor. One of them passed all 4 checks.

The 3 Weeks

First 20 swings, I could feel my hands settling into the perfect neutral grip.

A few sessions in, the ball was noticeably straighter. Not perfect, but much better than usual.

About 3 weeks, and I’d stopped thinking about my grip. My hands had the muscle memory memorized.

All 5, Side By Side

What Actually Changed

I know where the ball is going before I hit it. That’s what I was trying to buy with $450 of driver and 5 months of plastic.

I stopped aiming at the left trees to allow for the slice. I aim at the target now, like a normal person.

Last month somebody said “that’s good, pick it up.” First time in months.

Alex Again

Months later played with Alex again. My buddy’s son.

The one who asked me, at the top of this page, why my 22 years of golf still looked like a beginner’s.

By this time, I’d been training with the TrueGrip 2.0 for about 3 months.

I’m on the first tee, standing over the ball, and I can see him off to the side shifting his weight while he waits for me to tee off.

That used to be the worst 10 seconds of my week.

Then I pured it. Straight down the middle.

“Oh, nice shot.”

And he meant it.

By the end of the round, he asked me.

“Your swing looks so much better. What did you change?”

I was almost embarrassed to admit it.

I hadn’t changed my swing at all.

I just fixed the one thing that was throwing it away.

The Best Money I’ve Spent On My Game

I’m not the kind of guy who tells people what to buy.

But if you asked me on the first tee what the best money I ever spent on my game was, I’d point at the TrueGrip 2.0 in my bag.

26,384 golfers have used it to fix their slice. I'm one of them now.

Before I ordered, I checked the terms.

GameSwing backs it with a 30-day unconditional money-back guarantee. If it isn't worth every penny, one email gets a full refund.

You keep the trainer. No return shipping, no questions, no runaround.

Then I did the math on the old way.

$200 lessons. A $450 driver. Four pieces of plastic and a season I don’t get back.

Thousands of dollars, all aimed at the wrong thing.

Picture your drives finishing where you were actually aiming.

Your handicap dropping without touching a single thing in your swing.

Your buddies asking what changed.

All because your hands finally stopped sliding.

Questions I Got Asked

Will it go over jumbo grips?

Yes, and it’s the reason it’s on this page. The TrueGrip 2.0 is the only one I found that consistently fits all grips, standard, midsize and jumbo.

Is it going to overcorrect me into a hook like other grip trainers?

That’s exactly what happened to me, so I understand the fear. A trainer built to fight a slice doesn’t stop at neutral. It pushes your hands past neutral and turns it into a hook. This one is built to find neutral and hold you there, and my misses got smaller instead of changing sides.

How long before anything changes?

I felt my hands sitting somewhere new within 20 swings. It took me a few sessions before the ball looked different. And it was about 3 weeks before I stopped thinking about my grip at all.

Does it come off, or is it stuck on one club?

It clips on and off any full-swing club. Mine moves from the driver to a 7 iron in about 2 seconds. The bolt-on type is the whole category I refused to buy.

P.S.

If you still don’t know which version of you is going to show up on the first tee, I’ve been there for 22 years, and it isn’t your swing.

Your hands slide off neutral a few degrees at a time and you never feel it happen. By the time the ball tells you, it’s already gone right. A grip trainer exists to lock them there so they can’t slide, and that is the entire job.

Almost nothing on that shelf does it. It’s a combination lock with 4 digits: it has to fit your hand, fit the grips you already play, hold you at the top and not just at address, and come off so it moves through your bag. Miss one and it doesn’t half open. It doesn’t open.

I bought 5. One had all 4. The TrueGrip 2.0 fits standard through to jumbo, it’s stress-tested polycarbonate instead of the plastic that snapped in my hands, it locks both hands and holds through a full swing, and it clips on and off any full-swing club you own.

Terms, plainly. It normally sells for $100. Right now it's buy one get one free for $40, so two of them cost less than a tenth of what I spent on one driver that did nothing. 30-day money-back guarantee, any reason at all, one email. You keep the trainer. There is nothing to ship back.

Nobody has ever walked off a course asking the guy with the prettiest swing what his secret was. They ask the guy who hit every fairway.
